At $2400, it ain't cheap, but it looks like a lot of fun.

Or you could purchase 3 shotguns strategically and covertly place them. A rude awakening for a home invader(s).If you really feel the need for a Tatical semi automatic shotgun google AK saga shotgun...... like half the price
or you could by a Mossy 500 or Rem. 860 with a few 1000 rounds at the same price.
